PIPE DRIVING AND PULLING MACHINE.

Application filed October 26. 1927. Serial No. 228,966.

This invention relates to a combined pipe driving and pulling machinewhich may he effectively operated at different degrees.

, An object of the invention comprehen'ds gripping members adapted forbiting engagement with the pipe to hold the same against motion in onedirection and forsliding the pipe in a reverse direction.

Another object it of the invention compre- 1o hends a single handlemember adapted to simultaneously operate the gripping members.

A further object of the invention comprehends carriage members for thegripping members.

More specifically stated the grippin mem-.

bers are provided with interchangeable jaw faces to accommodate pipes ofdifferent sizes.

With the above and other objects in View, the invention further consistsof the following novel features and details of construction, to behereinafter more fully described,

illustrated in the accompanying drawings and pointed out in the appendedclaims. 111 the drawings:

Figure 1 is a top plan view of the invention parts being shown insection.

Figure 2 is a longitudinal sectional view taken 011 line 2-2 of Figure 1parts being shown in side elevation.

Figure 3 is a sectional View taken on line 33 of Figure 2.

Figure 4 is a perspective of one of the carriage members per se.Referring to the drawings in detail, where in like characters ofreference denote corrcsponding parts, the reference characters 10indicate base members, provided with standards 11.. Side angle plates1.2 and cross members 13 are adapted for connection with the standards11 to provide a frame structure, the purpose of which will be presentlyapparent. Cross strips 14 carried by the side plates 12 adjacent theconnection of the standards 11 therewith are adapted to interposebetween their upper sides and the adjacent undersides of the crossstrips 13, the ends of elongated guide plates 15.

Carriage members 16, composed of U- shaped frame structures are slidablymounted Within the channel portions defined by the angle plates 12,cross members and guide strips. The carriages arereversely disposed andhave parallel cars 17 projected there from adapted for connection withthe yoke portion 18 of a handle member 19 through the instrumentality ofpivoted links 20. Cross members 21 are employed to prevent flaring ofthe ends of the U-shaped frames. Plate members 22 disposed in spacedrelation within the corners of the frames of the carriages havepivotally mounted therebetween the adjacent ends of arms 23 havinginterchangeable pivotally mounted jaw faces 24 upon the working endsthereof.

Retractile springs 25 are employed for normally holding the jaw faces ofcompanion arms in juxtaposition. A pipe, such as i11- clicated at 26, isinserted within the frame and passed through openings 27 in the ends ofthe carriage frames. The jaw faces 24- of the arms 23 are disposed inalignment with. the registeringopenings 27 of the carriage frames toengage the pipe member.

The carriages are also interchangeable and the same may be arrzmged topush, hold and pull the pipe in different directions.

It is furthermore thought that the invention could be usefully employedin lifting jack construction.

The machine is designed to drive or pull a pipe or rod or similararticle, either horizontally or perpendicularly with a double actingmovement either by hand or power.

The main uses for the device would be the driving of pipe through dirtwithout excavating for pipe trenches, and for the pulling of pipe adistance without digging it out. Also thedevice may be employed for thelifting of pipe in a perpendicular position for driving The invention issusceptible of various changes in its form, proportions and minordetails of cons in reserved to make such changes as properly fall withinthe scope of the appended claims.

Having thus described the invention, what is claimed is 1. A pipedriving and pulling machine comprising a f 'ame structure, carriagemembers reversely arranged within the frame and having ears projectedtherefrom, a handle member mounted upon the frame and having connectionwith the ears of the carriages, arms pivotally connected with thecarriages and having jaw faces disposed in alignment with thelongitudinal center of the frame to engage pipe members extendedtherein.

2. A pipe driving and pulling machine comprising a frame member definingchannel raceways, carriage members slidably mounttruction, and the rightis hereed within the race-ways of the frame and having reglsteringopenings, ears projected from the carriages, a handle member pivotallymounted upon the frame and having plvotal connection wlth 'sa1d ears,arms pivotally mounted upon the carriages and dis posted at inclinationstoward Work extended Springs having connection between the arms ahandle. member pivotally mounted upon the and carriages for holding thejaw faces againstthe work.

. (Ii-A. pipe driving and pulling machine comprising a frame memberhaving raceways, Qa-rriages slidably mounted within the woe-aways andhaving registering openings,

frame, ears ext-ended from the carriage members in different directionsand having pivotal connection with the handle member at remote pointsthereon to facilitate relative movement of the carriage members incidentto the operation of the handle men'iber, spaced plates carried by thecarriage members, arm members pivotally mounted between the plates, jawfaces pivotally mounted for interchangeable lelation upon the outer endsthe arms for engagement with work extended within the frame, and springsestablishing connection between the arms and carriages. to hold and tomethe jaw faces against their work.

In. testimmiy whereof I afiix my signature.
